METHODS OF SONICALLY ACTIVATING CEMENT COMPOSITIONS
First Claim
Patent Images
1. A method of treating a subterranean formation, comprising:
- placing a settable composition including a capsule in a wellbore, wherein the capsule is used to increase a setting rate in response to a sonic signal; and
transmitting the sonic signal to at least a portion of the settable composition to release an activator from the capsule, wherein the activator is configured to increase setting rate of the settable composition.

Abstract
The present disclosure is directed to a system and method for sonically activating cement slurries. In some implementations, a method of treating a subterranean formation includes positioning a settable composition including a capsule in a wellbore. The capsule is used to increase a setting rate in response to at least sonic signals. A sonic signal is transmitted to at least a portion of the settable composition to release an activator from the capsule.

8. A method of cementing in a subterranean formation, comprising:
-
placing a cement composition including a capsule in a wellbore, wherein the capsule encapsulates an activator configured to increase a setting rate of the cement composition; and transmitting a sonic signal to at least a portion of the cement composition to release the activator from the encapsulating capsule. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
